Rice, wheat, and corn are the grains that have been cultivated with the longest history in our count

Among rice, wheat, corn and soybeans, rice and soybeans were the earliest cultivated by the Chinese. Rice has been in the Yangtze River basin in China since 7,000 years ago.

began to appear. Wheat belongs to the gramineous plant, the basin of the two rivers.

It was the first region in the world to start growing wheat. Corn is native to Central and South America, and China's main production areas are in the mountainous areas of Northeast China, North China and Southwest China. Soybeans have been cultivated in China for 5,000 years and are an important food crop.

One. Introduction to Rice and Soybeans.

1. Rice.

1. Rice is the country of origin of China and India, and the ancestors of the Yangtze River basin in China have cultivated rice as early as 7,000 years ago. Generally, our common types of rice are indica and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice, which are all varieties that are often eaten in daily life. Other classifications of rice, although uncommon, also have their uses.

2. Rice is one of the staple foods of half of the world's population, in addition to daily rice consumption, it can also be used for brewing and sugar as industrial raw materials, and rice husks and rice stalks can be used as livestock feed. The main rice-producing areas in China are mainly in Northeast China.

Yangtze River Basin, Pearl River Basin.

Rice is a direct cash crop.

Rice is the staple food of the people of Northeast China and the South of China.

2. Soybeans. 1. Soybeans are native to our country, and they are suitable for planting in general areas. As one of the important food crops in China, it has been cultivated for 5,000 years.

2. Northeast China is the main production area, which is a kind of seed rich in plant protein.

quality crops. Soybeans are most commonly used to make various soy products, to extract soybean oil, to brew soy sauce, and to extract protein.

The oldest cultivation in China should be rice, as early as 10,000 years ago, there was an agricultural civilization, that is, from which time, rice in China began to be planted.

In essence, there is no particularly big difference, the requirements for the soil are relatively high, we must choose fertile soil, there are many different planting methods in the process of planting, we must strengthen learning and management, and we must do a good job in preventing pests and diseases, and we must insist on watering and fertilizing.

The appearance and morphology are different, the growth environment is different, the distribution range is also different, the nutrient structure used is also different, and the temperature and water required are also different.

The planting method is different, the varieties planted are different, the land is different, the weather is different, and the amount of water is also different.

There are differences in appearance, in quality, in production, in watering, in planting.

The largest food crops in our country are rice and corn, not wheat.

Wheat is the most important food crop in China, accounting for about one-third of China's total grain production, with about 30 million tons of wheat produced each year. Wheat is the main food ** of the Chinese people and the main guarantee of China's food security. Wheat is planted in about one-third of China's total crop area and is the most important food crop in China.

The yield of wheat not only meets the daily needs of the Chinese people, but can also be exported to all parts of the world.

Corn can not only be used as a vegetable to eat, but also as feed for livestock, can also be deep processing, its use involves all aspects, it can be said that corn in many areas of our country in the food culture, occupies an extremely important position. But many friends may not know that corn is not a native crop in China, but a foreign product, and it has not been in China for a long time. It was introduced to China at the end of the Ming Dynasty about 500 years ago, but it is such an exotic crop, but it has become the largest food crop in China.

Tips for growing food crops

3-4 hours before sowing, generally soak the seeds in warm water of 50-55 for 10-15 minutes, soak them for 6-8 hours after cooling, and then rinse them with water for 1-2 times to sow seeds. The sowing method generally adopts live broadcasting, and the specific method is to plant from the town of Liangyuan, open two rows of shallow ditches with an interval of 50-60 cm on the furrow surface, and sow the processed slag stool seeds in the ditch with two grains per point, and cover the soil steadily.

Fresh corn is mainly sold in fresh ears, and it is best to sell it on the same day. If you need to sell over long distances, it is recommended to use cold chain logistics or other necessary preservation measures. Prevent corn ears from consuming their own nutrients and water due to respiration, resulting in a decrease in freshness and quality.

Which grain has been cultivated in our country for the longest time should be wheat and corn soybeans.

1. Rice is a straight-stem cereal crop of the grass family, and the main type is soil cultivation"Rice"(Always refers to freshwater rice). Rice is an important cereal widely cultivated in tropical Asia, and the southern part of China is the main rice-producing area, and it is cultivated in all northern provinces.

2. Sorghum is a plant of the Poaceae family. Commonly known as millet, millet, annual herbaceous plant, it is one of the main foods of the people of northern China. It is widely cultivated in the temperate and tropical zones of Eurasia, with the middle and upper reaches of the Yellow River in China as the main cultivation area, and a small amount of cultivation in other regions.

3. Mushroom, a general term for legumes.

4. Wheat, an annual or biennial herbaceous plant, has a variety of "wheat", "barley", "oats" and so on, usually referring to "wheat".

5. Millet, also known as"Millet"、"Mi (méi) seed"。In ancient times, it refers to an annual herbaceous plant called millet that is pale yellow, and is called yellow rice after peeling, which is slightly larger than millet.

6. Millet, an ancient grain crop, refers to millet or millet genus.

Extended Information: Shennong is the Yan Emperor, the founder of our country's agriculture. Shennong invented a large number of agricultural production tools and daily necessities. He found that the seeds of many plants were edible, so he sowed these seeds on the land, and kept experimenting, and finally found that the grain could be planted and harvested every year, so he selected five kinds of grains, namely liang, yac, wheat, millet and millet, and taught the people to plant them on a large scale, which became the main food of the people.

In the Tang Dynasty, rice was introduced from the ancient city of the south, and since then it has also become a staple food for people, and along with the five grains discovered in the Shennong period, it is called the "six grains" by people.

"Five grains" are the main crops in ancient China, millet, millet, wheat, soybean and hemp.

1. Millet: Millet shelled, that is, yellow rice, its seeds are sticky after cooking, and can be used to make wine and cakes. Because it is not conducive to digestion, "millet" is basically not used as a staple food now.

2. Millet: also known as millet, the growth is drought tolerant, there are many varieties, commonly known as "millet has five colors", there are white, red, yellow, black, orange, purple millet of various colors, and there are also sticky millet.

3. Wheat, a class of grasses, a kind of grains, divided into wheat, barley and other types.

4. Mushroom: A general term for beans, as the old saying goes: "Soybean is the strongest."

The ancient name is 尗, the Chinese name is the bean, and the word is now Shu. The general name of the beans. However, soybeans are called soybeans, bean seedlings are called Huo, and small beans are called wattles.

Bean products are also one of the favorite foods of the Chinese people.

5. Rice is a straight-stem cereal crop of the grass family, and the main type is "rice" cultivated with soil

1. The grain culture plays an important role and can be described as the origin of human civilization. According to authoritative data, human beings have observed traces of sorghum on stone tools hundreds of thousands of years ago, indicating that grains have given birth to human beings for more than 100,000 years. It cannot but be said to be a feat in the history of mankind that human beings have cultivated wild weeds into cereals, which gave birth to human civilization.

At the same time, it tells the world that human beings have an indissoluble relationship with grains. The grain painting is the highest artistic embodiment of the grain culture and the artistic portrayal of the grain culture.

2. Millet, millet and other crops in the five grains occupy a particularly important position in the primitive cultivation of the northern dryland because of their characteristics of drought tolerance, barrenness tolerance and short growth period. In the Spring and Autumn Period and the Warring States Period, the characteristics of "keeping the year easy to be" were discovered, and it also became an indispensable food for people at that time together with millet.

3. Whole grain paste is a powder made of various healthy grain raw materials after being roasted at low temperature, without puffing, and no instant solvent is added during processing, so it can retain the nutrients of the raw materials most completely.

4. Cereals mainly refer to the seeds of plants. It includes rice, wheat, soybeans, etc., and other miscellaneous grains, such as millet, black rice, buckwheat, oats, barley rice, sorghum, etc. Grains are processed as a staple food.

It mainly provides 50% 80% of calorie energy, 40% 70% protein, and more than 60% vitamin B1 to humans.

Wheat and rice are the most important staple foods in our lives and have a long history of cultivation in our country. But do you know which one has a longer history of cultivation, rice or wheat? You can't imagine it.

As early as 10,000 years ago, China produced an agricultural civilization. Edible plants are planted first, and then crops with high yields are selected and planted.

China's agrarian civilization can be traced back to the early Neolithic period. Legend has it that Shennong saw a big bird with a string of golden ears in its mouth and began to sow seeds, and made agricultural tools to teach people to farm, and since then China's agricultural civilization has been born.

According to archaeological discoveries, carbonized corn grains dating back 8,000 years were found at the Cishan site in Wu'an, Hebei Province, and rice remains from 10,000 years ago were found at the Shangshan site in Pujiang County, Zhejiang Province. It can be seen that the planting industry in our country has already begun at that time. China has a history of cultivating rice for at least 10,000 years, do you know this?

Crops in the pre-Qin period went through a process from more to less. At first, edible and non-toxic plants were cultivated, and with the improvement of people's awareness of crops, some low-yield and poor-tasting varieties were gradually phased out.

The historical relics of rice cultivation by the ancients are most concentrated in the southern part of Jiangsu and the northern part of Zhejiang in the Taihu Lake area, Hubei Province in the middle reaches of the Yangtze River, and the rest are scattered in Jiangxi, Fujian, Anhui, Guangdong, Yunnan, Taiwan and other provinces.

The cultivation technique of rice has also been continuously improved, from one season a year to two or even three crops, for example, in the Ming Dynasty, three crops of rice appeared.

Having said so much about rice, when did wheat appear? Wheat is not actually native to our country. Wheat originated in West Asia and entered China about 5,000 years ago. It is less than half of the history of rice cultivation.

After a long journey, wheat gradually adapted to the soil environment of our country and became one of the most successful exotic crops. It has played an important role in the process of China's agricultural civilization.

Since the emergence of wheat in China, it has gone through a process of promotion from west to east and from north to south, and it was not until the Tang and Song dynasties that the positioning in China was basically completed. The popularization of wheat has changed the planting structure of grain crops in China, and also changed the food habits of the Chinese people.

The four main types of grain produced by agricultural cultivation in China are wheat, rice, corn, and soybeans. Among them, the main rice producing areas are mainly the Yangtze River Basin, the Pearl River Basin, and the Northeast Region. Rice is a direct cash crop, rice is the staple food of Chinese residents, the current domestic rice planting area is 100 million mu of conventional rice, and the planting area of hybrid rice is 200 million mu.

China is the secondary center of wheat origin, China's wheat cultivation throughout the country, the Ministry of Agriculture shows that the main wheat producing areas are: Hebei, Shanxi, Henan, Shandong, Anhui, Hubei, Jiangsu, Sichuan, Shaanxi, etc., of which Henan is the largest province in China's wheat production, accounting for about a quarter of the country's wheat production. In 2019, China's wheat production exceeded 100 million tons.

Corn is an important feed for animal husbandry, aquaculture, aquaculture, etc., and is also one of the indispensable raw materials for food, medical and health, light industry, chemical industry, etc. In 2019, China's corn production was 100 million tons, and the consumption was 100 million tons.

In 2019, China's soybean production increased by 13% year-on-year, and the country's total grain output also increased slightly, hitting a record high. Soybean production increased to 18.1 million tonnes in 2019, up from 15.95 million tonnes in the previous year.
